Long‐term health consequences of COVID‐19 in survivors hospitalised at a tertiary care hospital and their correlation with acute COVID‐19 severity and associated risk factors

Abstract

AbstractObjectivesTo determine post‐COVID syndromes in the Indian population, correlating a wide spectrum of post‐COVID manifestations with acute disease severity and associated risk factors.BackgroundPost‐COVID Syndrome (PCS) is defined as signs and symptoms that develop during or after acute COVID‐19 infection.Design of StudyThis is a prospective observational cohort with repetitive measurements.MethodsThe study followed RT‐PCR confirmed COVID‐19‐positive survivors discharged from HAHC Hospital, New Delhi, for a period of 12 weeks. The patients were interviewed over the phone at 4 weeks and 12 weeks from the onset of symptoms for evaluation of clinical symptoms and health‐related quality of life parameters.ResultsA total of 200 patients completed the study. At the baseline, 50% of the patients were categorised as severe based on their acute infection assessment. At 12 weeks after symptom onset, fatigue (23.5%), hair loss (12.5%) and dyspnea (9%) were the main persistent symptoms. The incidence of hair loss (12.5%), memory loss (4.5%) and brain fog (5%) were found to be increased as compared to the acute infection period. Severity of the acute COVID infection behaved as an independent predictor for the development of PCS, with high odds of experiencing persistent cough (OR = 13.1), memory loss (OR = 5.2) and fatigue (OR = 3.3). Further, 30% of subjects in the severe group experienced statistically significant fatigue at 12 weeks (p < .05).ConclusionFrom the results of our study, it can be concluded that there is a huge disease burden of post‐COVID Syndrome (PCS). The PCS comprised multisystem symptoms ranging from serious complaints of dyspnea, memory loss and brain fog to non‐serious complaints of fatigue and hair loss. Severity of the acute COVID infection behaved as an independent predictor for the development of PCS. Our findings strongly recommend vaccination against COVID‐19, for protection from disease severity as well as prevention of PCS.Relevance to Clinical PracticeThe findings of our study support the multidisciplinary approach required for the management of PCS with a team comprising of physicians, nurses, physiotherapists and psychiatrists working in close coordination for the rehabilitation of these patients. As nurses are considered the most trusted professionals in the community and the class of health workers associated with rehabilitation, focus should be given to educating them on PCS, which would prove to be an important strategy for efficient monitoring and long‐term management of COVID‐19 survivors.
